Some Applications of Trigonometry

 

 

 

  • Line of sight: The imaginary line drawn from the eye of the observer to the object, when the observer is looking at it is called the line of sight,

 

 

Note: Line of sight is called the line of vision.

 

  • Angle of elevation: The angle formed by the line of sight with the horizontal when the object is above the horizontal level is called the angle of elevation,


                               

 

Note: When the observer looks at an object raising his, head an angle of elevation is formed.

 

  • Angle of depression: The angle formed by the line of sight with the horizontal when the object is below the horizontal level is called the angle of depression.


                

 

Note: When the observer looks at an object lowering his head, an angle of depression is formed.

 

  • The height or length of an object or the distance between two distant objects can be determined with the help of trigonometric ratios.
